Write a program to return a function using class in C Plus Plus?
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.

Different types of pointers in c language?
... are usable. void pointer (generic pointer) : a special type of pointer which point to some data of no specific types. void *p; null pointer : a special type of pointer which point nowhere. it is usually used to check if a pointer is pointing to a null or free the pointer during deallocation of memory in dynamic memory allocation; it is define by using the predefine constant NULL int *p=NULL; wild pointer : uninitialized pointer. it hold a garbage value. i.e it is not pointing to any memory location yet. dangling pointer: pointer pointing to a destroyed variable. it usually happen during dynamic memory allocation when the object is destroyed but not free and the pointer is still pointing to the destroy object.

Your mouse pointer shows busy icon and it flickers how can you solve your problem?
This problem can be solved by waiting for the computer to finish executing the program. If it persists, it is usually due the program crashed, and the mouse pointer can be restored by terminating the program using Task Manager.
Call by reference using pointer in c plus plus?
Example: void foo( MyClass& object ){} // function with call by reference signature MyClass* p = new MyClass(); // instantiate a pointer to MyClass foo( *p ); // call by reference using the pointer
What is the use of function in c?
using function we can call the function in the program any where. by using functions we can reduce the code redundancy

Why you are using VOID in C programming?
You don't use 'VOID', but 'void'. It means different things, such as:- void as function type means no return value- void as function parameter means no parameters- 'void *' as pointer-types means generic pointer

What is a segmentation fault?
An error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers in the source code, dereferencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
